Analysis

Hector J. Crespo Febles has managed 1 resolved case within Tech Center 2600 and Art Unit 2653. This case resulted in an allowance rate of 100.0 percent. Because the 100.0 percent rate is based on 1 resolved case, it represents the entirety of the examiner's current track record in this unit.

The median days to allowance for this resolution was 776. The data shows an interview lift of 0.0 percent, which means the allowance rate for cases with interviews is the same as the overall allowance rate. Practitioners should note that with the resolved case, these figures may shift as the examiner processes more applications.

The 776 median days to allowance provides a data point for timing in Art Unit 2653. The 0.0 percent interview lift indicates that the successful outcome was achieved without a recorded change in probability from an interview. As the examiner resolves more cases, the relationship between the allowance rate and the lift will become clearer.
